It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1 and 2, an embodiment of the present invention provides a capacitive touch holster keyboard, including: the key structure comprises a key cap 10, an elastic control member 20, a conductive film circuit board 30, a touch sensing film 40 and a keyboard touch circuit board, wherein the elastic control member 20 is arranged below the key cap 10; the conductive thin film circuit board 30 is disposed under the elastic control member 20; in use, as shown in fig. 1, a user can place a finger on the key cap 10, press the key cap 10 to press the elastic control member 20 downward through the key cap 10, and press the conductive thin film circuit board 30 through the elastic control member 20 to make the circuit contacts of the conductive thin film circuit board 30 conductive, thereby generating a keyboard pressing signal.

The touch sensitive film 40 is disposed under the elastic control 20; as shown in fig. 1, the state of a finger placed on the key cap 10 by a user can be detected through the touch sensing film 40, and further, in an embodiment of the present invention, the touch sensing film 40 is a capacitive sensing film. Because the capacitive sensing film has a sensing distance, when a finger is placed on the keycap 10 and moves left, right, front, back or up and down, the capacitive sensing film can output different capacitive sensing signals, and the gesture state of the finger can be acquired by reading the value of the capacitive sensing signals.

The keyboard touch circuit board is respectively connected with the conductive thin film circuit board 30 and the touch sensing film 40, so as to acquire key information through the conductive thin film circuit board 30, acquire touch information through the touch sensing film 40, and perform information input or control on the electronic device according to the key information and the touch information. As shown in fig. 2, the keyboard touch circuit board may be connected to the conductive thin film circuit board 30 by a flat cable connection line. In this way, the conductive thin film circuit board 30 can detect the pressing signals of the keys of the keyboard and output the pressing signals, the pressing signals form the keyboard pressing signals, and the keyboard touch circuit board can send the keyboard pressing signals to the electronic device or send the keyboard pressing signals to the electronic device after coding, so as to perform keyboard input or control on the electronic device. Similarly, the keyboard touch circuit board may be connected to the touch sensing film 40 through a flat cable connecting wire. In this way, the state information of the fingers on the respective keys of the keyboard can be detected by the touch sensing film 40. And outputting state signals of each finger placed on the key cap 10 of the keyboard, wherein the state signals of each finger constitute the touch information, the keyboard touch circuit board can acquire the touch information, and the keyboard touch circuit board can acquire the state of each finger placed on the key cap 10 of the keyboard through the touch information. For example, it can be obtained whether the user has several fingers on the key cap 10 and the fingers are moving; when the user's finger is not placed on the key cap 10 or is in a depressed state, it is in a typing state, and the touch is not responded. When the keyboard is obtained, a single finger or two fingers and three fingers slide, the keyboard is in a normal touch state. At this time, the keyboard touch control circuit board can send the touch control information to the electronic equipment or send the touch control information to the electronic equipment after the touch control information is coded, so that the electronic equipment is controlled. In one embodiment of the invention, the number of the moving fingers can be defined according to the actual situation.

Further, in an embodiment of the present invention, the touch sensing film 40 is disposed at a position of the front surface or the back surface of the conductive thin film circuit board 30 by means of pasting. Since the conductive thin film circuit board 30 has a thin film structure, it has a certain flexibility and its surface is relatively smooth. Therefore, the touch sensing film 40 may be attached to the surface of the conductive thin film circuit board 30, since the touch sensing film 40 also has a certain flexibility. Thus, even if the touch sensing film 40 is attached to the upper surface of the conductive thin film circuit board 30, the pressing of the elastic control member 20 against the conductive thin film circuit board 30 is not blocked. By means of pasting, the structure between the touch sensing film 40 and the conductive thin film circuit board 30 is more compact, and the touch sensing film 40 is not easy to displace.

In this way, the elastic control members 20 can be chucked and fixed by the chucking member 5011, since the chucking member 5011 is fixedly connected with the elastic control members 20 passing through the conductive thin film circuit board 30, the touch sensing film 40 and the like. In this way, the conductive thin film circuit board 30 and the touch sensing film 40 can be fixed.

Further, in an embodiment of the present invention, the touch sensing film 40 is disposed at a front or a back of the mounting substrate 50 by means of pasting. In an embodiment of the present invention, when the mounting substrate 50 is made of a non-metal material, the touch sensing film 40 may also be disposed on the front surface or the back surface of the mounting substrate 50 by a pasting method.
